SlPHON-BOTTLE.,

SPECIFICATION forming part of Letters Patent No. 732,038, dated June 30, 1903.

Application filed March 27, 1902.

To all whom it may concern.-

Be it known that I, WOODBRIDGE H. BIRCH- MORE, a subject of the King of Great Britain, residing in the borough of Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Siphon-Bottles, of which the following is a specification.

Heretofore the metal tops of siphon-bottles have been secured thereto by means of a metal collar swaged or otherwise solidly secured to the neck of the bottle to which the metal top is attached. When a siphon-bottle of this type is heated, as is sometimes done in order to pasteurize its contents, the difference in expansion between the glass of the bottle and the closely-fitting metal collar is liable to cause the glass to break.

The object of my improvements is to obviate this defect and at the same time provide a simpler and more economical construction. To this end I provide the neck of the bottle with ears or lugs made integral therewith, which are adapted to engage in horizontallyextended slots or bayonet-joints in a collar which forms a part of the metal top and loosely surrounds the bottle-neck when the top is in place thereon. The lower sides of the slots in the collar have a slight upward inclination, so that when the collar is turned the ears on the bottle-neck ride up thereon and the top is drawn tightly down to the bottle and secured thereon. By inter-posing a suitable washer between the metal top and the top of the bottle the joint between the two is made gas-tight, and the elasticity of the washer will accommodate the difference in the expansion of the bottle and cap when the bottle is heated. The opening of the bottle-neck is made slightly flaring, and the glass discharge-tube which extends down into the bottle is provided with a head which conforms in shape to the bottle-mouth. A washer is interposed between the head of the tube and the bottle, and when the metal top is drawn down upon the bottle it forces the head ofthe tube down upon this washer and further secures the tightness of the vessel. A siphon-bottle of this form is extremely simple and economical to manufacture, its parts can be easily assembled or separated, as deshowing the slots in the collar.

sired, and the application of heat will not cause the bottle-neck to be broken by reason of its being closely gripped by a metal collar.

My invention will be best understood by reference to the accompanying drawings, in which the same letters of reference indicate corresponding parts in the diflerent figures.

Referring to the drawings, Figure 1 is a perspective showing the metal top attached to the bottle. Fig. 2 is a vertical section along the line 2 2 in Fig. 1. Fig. 3 is a perspective of the lower part of the metal top inverted, Fig. 4: is a view of the bottle-neck seen from above. Fig. 5 shows the washer around the head of the glass tube, and Fig. 6 the washer between the metal top and the bottle.

A indicates the neck of the bottle, provided with two or more ears or lugs a a, integral therewith. B is the metal top of the siphon, having a collar 0, which when the top is in place surrounds the neck of the bottle. The collar O is provided with horizontally-extended slots or bayonet-joints c 0, adapted to receive the lugs a a. The lower edges of the slots 0 0 have a slight upward inclination, so that when the lugs a a are engaged therein and the collar is turned the top B is drawn down upon the washer D, of 'pergamentized paper or othersuitable material, which is in portion, the

terposed between a shouldered top B, and the bottle-neck A.

E is the glass discharge-tube. It is provided with a conical head e, with whichthe upwardly-flaring conical opening of the bottle-mouth correspondsin shape and which is surrounded when the tube is in place with a washer F, of pergamentized paper or other suitable material. The top or cap B has a passage 5, adapted to register with the discharge-tube E. The parts are so proportioned that when the tube E is looselyinserted in the bottle-neck the upper surface of the head 6 is slightly raised above the upper surface of the bottle-neck by the washer F and is partly overlapped by the washer D.

In assembling the parts the tube E is put in place, with the washer Faround the head 6, the washer D is placed upon the top of the bottle, and the top B is placed upon the bottle, so that the lugs a (L enter the slots 0 c in the collar 0. Upon rotating the top B so that the lugs enter the slots it is drawn down upon the washer D, and the head 0 of the tube E is forced against the washer F, so that an air-tight joint is formed and leakage of gas from the bottle is prevented.

It Will be evident that a siphon-bottle constructed in accordance with my invention can be cheaply manufactured, that the parts can be readily assembled or separated for the purpose of cleansing the bottle, and that the bottle may be heated without danger of being broken on account of the difference of expansion between the glass and metal parts, as the elasticity of the washers will allow for the difierence in the expansion of thebottle and the cap. The advantages of this will be readily apparent to those skilled in the art.

What I claim as new, and desire to secure by Letters Patent, is-- 1. In a siphon-bottle, the combination with the bottle proper, having its neck provided interiorly with an upwardly flaring coneshaped seat, a discharge-tube having an enlarged cone-shaped head conforming to said seat, a bottle-cap adapted to fit over said neck and provided above said discharge-tube with a shoulder and a central passage registering with said tube and securing means for forcing said cap upon said bottle-neck so as to force the enlarged end of said discharge-tube into said conical seat, substantially as de scribed.

2. In a siphon-bottle, the combination with the bottle proper, having its neck provided interiorly with an upwardly-flaring coneshaped seat, a discharge-tube having an enlarged cone-shaped head conforming to said seat, a bottle-cap adapted to fit over said neck and provided above said discharge-tube with a shoulder and a central passage registering with said tube, a perforated washer interposed between said shoulder of said cap, and the upper end of the enlarged portion of said discharge-tube, and securing devices for forcing said cap downward on the bottle-neck and seating the enlarged portion of the discharge-tube in the conical seat of the bottleneck, substantially as described.

3. In a siphon-bottle, the combination with the bottle proper having its neck provided iuteriorly with an upwardly flaring coneshaped seat, a discharge-tube having an enlarged cone-shaped head conforming to said seat, a bottle-cap adapted to fit over said neck and provided above said discharge-tube with a shoulder and a central passage registering with said tube, a perforated washer interposed between said shoulder of said cap and the upper end of the enlarged portion of said discharge-tube, a conical washer interposed between the enlarged head of said dischargetube and said conical seat and securing devices for connecting the bottle-cap to the bottleneck constructed to force the said cap downward and force said enlarged head of the discharge-tube into said seat, substantially as described.

4. In a siphon-bottle, the combination with the bottle proper, having its neck provided interiorly with an upwardlyflaring coneshaped seat, a discharge-tube having an enlarged cone-shaped head conforming to said seat, a bottle-cap adapted to fit over said neck and provided above said discharge-tube with a shoulder and a central passage registering with said tube, a perforated washer interposed between said shoulder of said cap and the upper end of the enlarged portion of said discharge-tube, a conical washer interposed between the enlarged head of said dischargetube and said conical seat, lugs on said bottle-neck and inclined slotted portions formed on said cap for engaging said lugs to connect the cap to the'bottle-neck and force said enlarged portion of the discharge-tube into said conical seat, substantiallyas described.

In testimony whereof I have hereunto subscribed my name this 26th day of March, A. D. 1902.
